Polymer functional group
End groups are an important aspect of polymer synthesis and characterization. In polymer chemistry, they are functional groups that are at the very ends of a macromolecule or oligomer (IUPAC). In polymer synthesis, like condensation polymerization and free-radical types of polymerization, end-groups are commonly used and can be analyzed by nuclear magnetic resonance (NMR) t… WebIncorporation of Functional Groups into Polymers Prepared by ATRP Introduction. Functional groups increase the utility of polymers and are fundamental to the development of many aspects of structure-property relationships. The functionality present on the monomer units determines the solubility of the polymer in a given solvent.
